Linear Instability Signals the Initiation of Motion of a Twin Plane Under Load
by Chang-Tsan Lu and Kaushik Dayal
Abstract
Hi All,
i am doing my m. tech project on " FE modeling and validating to find stress intensity factor for a crack emanating from one rivet hole and approaching another rivet hole".I have developed the FE model in ANSYS and tabulated stress intensity factor at crack tip from different crack length. But to validate my result i want an mathematical model or formula. Please suggest me an formula to find KI at the crack tip for this problem.
I have extracted field output from ABAQUS odb file and I want to take log of that field. In ABAUQS scripting manual, in section 9.8.2 it has been mentioned that
log10(field output)= field output
When I am trying to do this compilation gives me error. "a float value required"
Please guide me if i am making any mistake
Also if possible, suggest how can I get rid of this problem?
I'm currently studying FEA/CFD and BEM for thermal simulation of custom dies within custom package mounted on custom PCB with encapsulate material (epoxy). I getting familar with CFD concept which seem overkill from ANSYS IcePack (too expensive) but exploring BEM technology from E3D in france (via Vishay).
I have access to MATLAB from other company to try it out for thermal modelling (BEM).
I'm working on blood vessels constitutive equations and i need some papers but i can't find them
i hope if you can send them to me
here is my mail: vahab.ahmadi.joneidi [at] gmail.com (vahab[dot]ahmadi[dot]joneidi[at]gmail[dot]com)
in need these papers:

Hi There,
I am modelling a soil nail wall with ABAQUS. I am wondering to know what interaction I am supposed to define for connecting nail to wall and nail to soil? By the way, I define soil as 2D plane strain and wall and beam as beam element.
